The utility model arranges the mounting plate, the placement groove and the baffle bar so that the rolling mill operating component and the rolling mill drive mechanism can be quickly disassembled from the rolling mill table, so that they can be quickly disassembled and repaired when a fault occurs in the later stage; further, by arranging a movable slider and a spring, the baffle bar can be automatically reset after being pulled, which further speeds up the later installation and fixation.
[0004] Although the above device can be quickly disassembled and repaired when a fault occurs in the later stage, there are still some problems when using the device:
[0005] 1. The device does not have a finished product cooling mechanism. Metals often need to be heated to a higher temperature before they can be rolled. Therefore, the temperature of the finished product after rolling is high, and people are easily burned when they use it directly.
[0006] 2. The device does not have a roller distance adjustment mechanism, and its calendering thickness is not adjustable. It can only extrude metal sheets of one thickness, and its use is relatively limited.
[0007] In view of the above situation, technical innovation is carried out on the basis of the existing metal calender. Utility Model Content
[0008] The purpose of the utility model is to provide an adjustable metal calender to solve the problems raised in the above background technology.
[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable metal calender, comprising a fixed roller frame and a base, a cooling fan is fixed to the rear end of the fixed roller frame, and a micro water pump is fixed to the rear end of the cooling fan, the output end of the micro water pump is connected to an atomizing nozzle, and the input end of the micro water pump is connected to a connecting hose, the base is fixed to the bottom end of the fixed roller frame, and a grid is fixed to the rear end of the top wall of the base, a water tank is provided at the internal front end of the base, and the water tank is communicated with the connecting hose, a reducer is fixed to one side of the fixed roller frame, and a calendering motor is fixed to the side of the reducer away from the fixed roller frame, and an active calendering roller is fixed to the output end of the reducer.

[0014] Furthermore, support components are fixed on both left and right sides of the bottom end of the base, and the support components include support feet and foot pads, and the bottom ends of the support feet are bonded with foot pads.
[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the device is provided with a cooling mechanism, which can quickly cool the metal sheet workpiece after calendering, thereby avoiding burns to the hands of people when taking it, which is beneficial to improving the safety of the device; at the same time, the device is provided with a roller gap adjustment mechanism, which can adjust the roller gap of the calendering roller, so that the device can extrude workpieces of different thicknesses, which is beneficial to improving the practicality of the device.
[0016] 1. The utility model is provided with a cooling fan, a micro water pump, an atomizing nozzle, a connecting hose, a grid and a water tank.

The grid not only increases the contact area between the metal sheet and the air, further improves the cooling speed, but also enables the airflow blown by the cooling fan to pass smoothly, reducing the possibility of liquid mist being carried around by the airflow. Through the above structure, the device can quickly cool the calendered metal sheet workpiece, thereby avoiding hand scalding when personnel take it, which is conducive to improving the safety of the device.

[0025] like Figure 1-3As shown, an adjustable metal calender comprises a fixed roller frame 1 and a base 6, a cooling fan 2 is fixed to the rear end of the fixed roller frame 1, and a micro water pump 3 is fixed to the rear end of the cooling fan 2, the output end of the micro water pump 3 is connected to an atomizing nozzle 4, and the input end of the micro water pump 3 is connected to a connecting hose 5, the base 6 is fixed to the bottom end of the fixed roller frame 1, and a grid frame 7 is fixed to the rear end of the top wall of the base 6, a water tank 8 is arranged at the front end of the inner part of the base 6, and the water tank 8 is communicated with the connecting hose 5, a reducer 9 is fixed to one side of the fixed roller frame 1, and a calendering motor 10 is fixed to the side of the reducer 9 away from the fixed roller frame 1, and an active calendering roller 11 is fixed to the output end of the reducer 9, when the device is finished calendering, the calendered workpiece will fall on the grid frame 7, at this time the staff can turn on the cooling switch, and the micro water pump 3 will pass through the connecting hose 5. The hose 5 draws water from the water tank 8 and sprays it onto the surface of the rolled metal sheet through the atomizing nozzle 4, thereby cooling the metal sheet. At the same time, the cooling fan 2 blows out an airflow to cool the metal sheet. The airflow can accelerate the evaporation of the liquid on the surface of the metal sheet, thereby increasing the cooling rate, thereby rapidly reducing the temperature of the rolled metal sheet, making it convenient for personnel to quickly take away the rolled metal sheet and avoid hand burns when taking the metal sheet. The grid 7 not only increases the contact area between the metal sheet and the air, further increasing the cooling rate, but also enables the airflow blown out by the cooling fan 2 to pass smoothly, thereby reducing the possibility of liquid mist being carried around by the airflow. Through the above structure, the device can rapidly cool the rolled metal sheet workpiece, thereby avoiding hand burns when personnel take it, which is beneficial to improving the safety of the device.
[0026] like Figure 1 and Figure 3As shown, a hydraulic cylinder 12 is fixed to the top of the fixed roller frame 1, and a movable roller frame 13 is fixed to the output end of the hydraulic cylinder 12, a driven calendering roller 14 is arranged on the inner side of the movable roller frame 13, and the driven calendering roller 14 is rotatably connected to the movable roller frame 13, sliders 15 are fixed on the left and right sides of the movable roller frame 13, and a slide rail 16 is arranged on the inner side of the slider 15, the fixed roller frame 1 and the base 6 are both made of stainless steel, and the base 6 and the fixed roller frame 1 are welded and fixed, support components 17 are fixed on the left and right sides of the bottom end of the base 6, and the support component 17 includes a support foot 1701 and a foot pad 1702, and the bottom end of the support foot 1701 is bonded with the foot pad 1702. When the staff needs to adjust the calendering thickness of the device, The hydraulic cylinder 12 can be operated to extend or contract. When the hydraulic cylinder 12 extends, it can drive the movable roller frame 13 to press down, so that the driven calendering roller 14 is close to the active calendering roller 11, reducing the gap between the active calendering roller 11 and the driven calendering roller 14, reducing the calendering thickness, and vice versa, the calendering thickness can be increased. The two slide rails 16 are fixed to the inner walls of the fixed roller frame 1. In the process of the hydraulic cylinder 12 driving the movable roller frame 13 to rise and fall, the slider 15 and the slide rail 16 can effectively limit the movable roller frame 13 to avoid inconsistent heights on both sides. Through the above structure, the staff can adjust the roller spacing of the calendering roller, so that the device can extrude workpieces of different thicknesses, which is conducive to improving the practicality of the device.
[0027] In summary: when using the adjustable metal calender, first, a control panel is provided on the outside of the base 6, and the control panel is electrically connected to the micro water pump 3, the calendering motor 10 and the hydraulic cylinder 12. The staff can control the micro water pump 3, the calendering motor 10 and the hydraulic cylinder 12 through the control panel. During calendering, the staff can place the workpiece between the active calendering roller 11 and the driven calendering roller 14, and turn on the calendering motor 10. At this time, the calendering motor 10 drives the active calendering roller 11 to rotate through the reducer 9, thereby rolling the workpiece into the active calendering roller 11 and the driven calendering roller 14. The workpiece 1702 is calendered between the movable calendering rollers 14, and the calendered workpiece will fall on the grid 7. The foot pad 1702 is made of rubber. During the calendering process, the foot pad 1702 can play a certain role in shock absorption and anti-skid. When the device is finished calendering, the calendered workpiece will fall on the grid 7. At this time, the staff can turn on the cooling switch, and the micro water pump 3 will draw water from the water tank 8 through the connecting hose 5, and spray it on the surface of the calendered metal sheet through the atomizing nozzle 4, so as to cool the metal sheet. At the same time, the cooling fan 2 will blow out airflow to cool the metal sheet. The airflow can accelerate the evaporation of the liquid on the surface of the metal sheet, thereby increasing the cooling speed, so that the temperature of the rolled metal sheet can be quickly reduced, which is convenient for personnel to quickly take away the rolled metal sheet and avoid hand burns when taking the metal sheet. The grid frame 7 not only increases the contact area between the metal sheet and the air, further increasing the cooling speed, but also enables the airflow blown by the cooling fan 2 to pass smoothly, reducing the possibility of liquid mist being carried around by the airflow. When the staff needs to adjust the rolling thickness of the device, the hydraulic cylinder 12 can be operated to extend or contract. When the hydraulic cylinder 12 is extended, it can drive the movable roller frame 13 to press down, so that the driven calendering roller 14 is close to the active calendering roller 11, reducing the gap between the active calendering roller 11 and the driven calendering roller 14, reducing the calendering thickness, and vice versa, the calendering thickness can be increased. The two slide rails 16 are fixed to the inner walls of the fixed roller frame 1. In the process of the hydraulic cylinder 12 driving the movable roller frame 13 to rise and fall, the slider 15 and the slide rail 16 can effectively limit the movable roller frame 13 to avoid inconsistent heights on both sides. This is the working principle of the adjustable metal calender.
[0028] The above are only preferred embodiments of the utility model, and do not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
